2019-6-11 · Once a firetube boiler is started up and is operating at its desired pressure, a firetube boiler can handle a sudden upward load surge better than a watertube boiler because of the large steam disengaging area. The drawback to this feature is once the pressure of a firetube is dropped, it takes longer to catch back up.

2016-4-12 · This problem coupled with the large boiler water content tended to make these boilers slow steamers. Improvement in boiler designs with better furnace location within the boiler shell and more scientific firetube layout has largely eliminated the problem. Large water content also makes the packaged firetube boiler an excellent selection for

2019-6-10 · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
